2 OSHA and Safety
ZiPline Conveyor is not responsible for ensuring that conveyors used in a system abide by OSHA
standards. Safety is of primary importance to our company, but as a product distributor we ask that
system integrators and end users conform with all applicable OSHA standards. We encourage that all
warnings in this manual are followed to avoid unnecessary risk.
Installation and Maintenance Manual: BZPDC
Published October 2019 Rev.A1 8
3 Model: BZPDC
The Belted Zero Pressure DC (BZPDC) Conveyor is designed with brushless 24V DC motor rollers. These
rollers are referred to as motor driven rollers (MDRs). BZPDC is used for product that needs to be
accumulated without contacting other product. This is accomplished with zones. BZPDC zones include an
MDR that drives a lead roller with tracking bands that drives a belt and a group of idler rollers. Photo
eyes, reflectors, and control cards are all used to identify when a zone should be running and when a
zone should be stopped.
Figure 1: BZPDC General Arrangement Exploded View
The model shown in Figure 1 serves as a reference to become familiar with the components and
terminology used in this manual. These terms will be used throughout the manual and are common
among many other ZiPline Conveyor product lines.
The model in Figure 1 shows a 5’ BZPDC bed section. The BZPDC has 4” roller centers and has (2) 30”
zones. The 30” zone is made up of (6) no groove idler rollers, (1) MDR, and (1) lead roller with grooves
(typically either poly-v or 2 groove) with two tracking bands. The lead roller and MDR each have either 2
grooves or poly-v grooves that allow them to be banded together with o-ring or poly-v bands,
respectively.
For incline applications, the lead roller can be selected to be a one-way roller. The one-way lead roller
can rotate either clockwise (CW) or counter-clockwise (CCW) only. Refer to Figure 12 in Appendix 1 to
determine which direction the one-way roller should rotate in a specific application. For decline
applications, certain MDRs can be selected to be a brake MDR. If the brake MDR option is not available,
a brake roller can be used as the lead roller in the zone. For incline and decline applications where a
Installation and Maintenance Manual: BZPDC
Published October 2019 Rev.A1 9
one-way roller, brake MDR, or brake roller is used, the recommended band type is poly-v because less
slip is experienced between the lead roller and MDR with poly-v bands relative to o-ring bands.
Each zone requires one photoeye and one reflector. The reflector is not needed if diffuse photoeyes are
used. In the specific configuration shown in Figure 1, a dual zone card is being used to control both
zones. While this is a standard configuration, it is also common to use one zone per card.
4 Receiving
Upon delivery of any ZiPline Conveyor, please review and check the following:
• The quantity of items received against the Bill of Lading.
• Complete a visual inspection of equipment to determine any damage that may have occurred
during shipping. If damage is present, document with pictures.
• Review Mark Number information and layout locations. More information can be found in
subsection 4.1.
If there are any missing or damaged components contact your ZiPline Conveyor representative with as
much detail as possible. If you are unsure of your ZiPline Conveyor representative, please contact
Customer Service at [email protected].
4.1 Mark Numbers
A mark number is a specific number given to a piece of equipment. A mark number is usually made up of
a single product line (RZPDC, RLVDC, BZPDC, etc.) but can contain many bed section lengths. They can
range from two inches to hundreds of feet. The mark number is used to help identify where the piece of
equipment will go within the system layout.
Every bed section of conveyor will have (2) stickers. One sticker on the infeed end of the bed, and one
sticker on the discharge end of the bed. Each sticker will contain the following information:
• ZiPline Project Number and Name
• Model Type
• Mark Number
• Match
• Piece
• Flow
Figure 2 shows stickers that would appear on an RZPDC that has two bed sections.
The match field on the stickers is used to indicate if two bed sections are to be spliced to one another.
As shown in Figure 2, the stickers where the two beds splice together both contain “Match: 1”. The
piece field defines the bed section number within the mark. The flow refers to the direction of product
flow along the conveyor system.

4.2 Skid Contents
Skids will contain varying combinations of conveyor sections, support structures, accessories, and
pertinent hardware. For protection of product integrity during shipping, accessories and supports may
be delivered on separate but labeled skids.
4.3 Skid Documentation
All shipments will contain a Bill of Lading for the delivery company, a skid label, and a skid manifest. Skid
labels have the contents of each shipped item located on the skid. Figure 3 shows a sample of a skid
label. These stickers are placed on the surface of each skid.

5 Installation
The installation supervisor should have elevation and layout prints with detailed information regarding
the placement of conveyor sections and support structures. This information is not the responsibility of
ZiPline Conveyor to provide unless otherwise specified.
1. Clear the workspace around the portion of the layout selected for installation.
2. Measure out from a constrained origin to start placement of supports. It is recommended that
snap chalk lines are used, or other methods of keeping a consistent line.
3. Use elevation layouts to determine the conveyor’s top of conveying surface.
4. Place the support type that the layout designates. Each support type has a corresponding mark
sticker.
5. Check the flow direction on the mark stickers to ensure that conveyors are mounted properly.
6. Place the conveyor onto the support structure and fasten it securely using the 3/8”-16 carriage
bolts and wiz nuts provided. The recommended torque specification is 26ft-lbs.
7. Attach any guide rail or miscellaneous accessories. For information on guide rail installation,
please reference the “ZiPline Side Cover and Guide Rail Installation Manual”
8. Check that the height of the infeed and discharge ends are correct per the system layout.
9. Lag the supports to the floor (or another permanent fixture).
Refer to the “ZiPline Conveyor Support Installation Manual” for more information on installing conveyor.
5.1 Installing underside covers
The underside covers are an accessory item for a BZPDC mark. The underside covers are shipped
separately on a skid. The overall width of the underside cover is approximately 1/8” less than the
between frame width of the bed section. All underside covers supplied come with underside cover splice
plates for installation.
The following instructions outline the operational procedure to install underside covers.
1. Identify the underside cover for the installed BZPDC section.
2. It is recommended to install one splice plate at every corner of the underside cover and at least
1-2 splice plates between the ends. Refer to Figure 4 that shows an exploded view of the splice
plate install on the side covers. The splice plate is installed using 3/8” carriage bolt and serrated
flange nut.

6 Maintenance and Operation
The longevity and proper functionality of ZiPline Conveyor is based upon standard operating practices
and general maintenance of equipment. Setting up a regular maintenance schedule will help to ensure
that products comply with the equipment’s warranty. Lockout/Tagout (LOTO) procedures should be
implemented before performing any maintenance.
Installation and Maintenance Manual: BZPDC
Published October 2019 Rev.A1 13
6.1 Safety During Operation
The list below explains a series of recommended precautions that should be taken when personnel are
near the equipment. This list is not intended to be the only precautions taken, but it serves as a guide of
important steps to follow.
• Only fully trained employees should operate or perform maintenance on conveyor. Proper
training should include the detailed description of fail-safes, stopping devices, or other
emergency regulations put in place.
• WARNING stickers should be replaced if worn or damaged.
• All personnel in the area should always be alerted prior to starting any conveyor. This process
may vary depending on the conditions and layout of the site, but it should use audible and visual
cues and all personnel should be made aware of the protocol.
• Operators should inspect the conveyor for damage, foreign objects, and verify all personnel is
clear of the equipment prior to engaging drive.
• Ensure that all areas are clear of objects prior to loading and unloading.
• No personnel should ever ride, climb, step, sit on, or otherwise put body weight on the
conveyor. Doing so puts both personnel and equipment at risk.
• Maintenance should be performed at regular intervals to assure the safety of operators and the
longest life of components. Should a component break during operation or prior to operation,
then LOTO instructions should be performed immediately to prevent exposure to hazards.
6.2 Maintenance Schedule
To prolong the life of the material handling equipment and reduce the risk of potential safety hazards, it
is vital that a preventative maintenance program be set in place and followed. The following instructions
will help identify key areas requiring maintenance.
6.2.1 Mechanical Service
• An auditory inspection of the equipment should be performed to identify any unusual noise that
may indicate that there is a problem with the equipment.
• Check all nuts and bolts to ensure bolts remain tight. MDR nuts should be torqued using a
torque wrench to each MDR’s torque specs. Please reference Table 1 for a list of common MDRs
and their torque requirements.
• O-rings, poly-v bands, and any other bands should be inspected for excessive wear, stretching or
slip and replaced as necessary.
• The recommended interval for maintenance is at least once every 6 months.

6.2.2 Electrical Service
• All ZiPline Conveyor DC products operate at either 24V or 48V, nominally.
• If adjustment of control card settings is required, refer to the respective technical manual listed
in Reference Documents, or contact ZiPline Support at [email protected].
• If there is a need to replace a DC control card, perform the following:
o De-energize associated power supply and remove respective side cover (if applicable)
o Adjust settings of replacement control card to match those of the existing control card.
o Remove the existing control card from the side frame for ease of cable disconnection:
▪ If the existing control card has a mounting plate, remove wiz nut securing
control card mounting plate to side frame.
▪ If the existing control card is secured to the conveyor side frame with anything
other than a mounting plate, install new securing material on the new control
card and reuse the securing material on the side frame.
o One at a time, remove all cables and connectors and plug them into the same respective
connection port on the new control card.
o If the control card in question has a mounting plate, remove the mounting plate secured
to the existing control card, and install it on the new control card (if the new control
card does not already have a mounting plate installed on it).
o Install the new control card on the conveyor side frame
o Re-energize associated power supply, check the lane for proper system functionality,
and reinstall the respective side cover (if applicable).
Never “hot swap” control cards (i.e. disconnect and reconnect power
connector on control cards without de-energizing respective power supply)
as there is an increased risk of damaging the new control card.
There is always a possibility that control card errors are being caused by
faulty communication cables (RJ45, CAT5, or CAT6) or problems with
adjacent cards connected via the communication cables.
• If cards or card fuses are blowing:
o Ensure there are no shorts in system power wiring
o Ensure all conveyor side frames are electrically bonded and provided a direct
connection to earth ground
o Ensure the control card DIP switch settings match those needed for the MDR (if
applicable)
o Ensure it is electrically connected if the associated conveyor zone has powered brake
roller
o Refer to the respective technical manual listed in the Reference Documents section of
this document if problems persist
When performing electrical work on ZiPline Conveyor, ensure adherence to
all applicable OSHA standards.
